Twapster is right. Conflict or "blood Diamonds" have been the cause of a great deal of violence and even wars resulting in thousands dying. In 2003 the United Nations Security Council formed the Kimberley Process Certification Scheme. No diamond producer is allowed to trade rough (uncut) diamonds with a country that is not a member of the Scheme and even then each and every rough diamond must be accounted for and approved for export. Countries to which rough diamonds are exported are similarly not allowed to accept them if they are not authorised and recorded. It doesn't matter if the diamond is valued at $1 million or a bit of rubbish worth $1 dollar. They are treated to same way.
This has reduced diamonds being used to fund wars. Also the treatment of people trying to avoid these restrictions are very harsh. I had to do a review of the Scheme as implemented in Thailand a few years ago and the Thais told me that they treat diamond smugglers the same as drug traffickers. needless to say the number of diamond smugglers in Thailand are effectively non-existent.
So if anyone finds a diamond in Australia I would suggest that you get it appraised to determine its value. If it is valuable and you want to cut it - don't do it in Australia as we really don't have anyone with the experience to do it properly, which the exception of Argyle who only cut their own stones. You would want to have it done in India and it will need a Kimberley Process Certificate to export it. Go see
